The magician scoops up a quantity of confetti from a box, filling the cup, and then allows it to trickle back into the box. He repeats this and then puts the lid on the cup. When the lid is removed the confetti has transformed into whatever the magician wishes, for example sweets or silk handkerchiefs. The design of the cup suggests that it was made by the British dealer Burtini. Once the possession of Cambridge magician Claude Perry.
